It's a dog when I take off from a stand still, I can literally put my foot to the floor and it won't move fast but it's slow to react and it lags but then kicks in.

Is there a schrader valve where I can hook up a pressure guage?

Thanks for the reply.

A while back I had my '06 Touring Edition at the dealership for some other work, while they had it I had them do a fuel system pressure check. I saw the gauge set up while installed on my PT and I believe there is a quick disconnect at the firewall, on the passenger side where the steel line comes into the engine compartment, that they unplugged and hooked up their gauge set to. The gauge set up was two gauges, similar to HVAC work, and they could check the fuel pump pressure, then turn a couple of valves and also check to see if the injectors are holding pressure. They let the gauges set to check any bleed down from the injectors as well.

Usually the symptoms are the opposite of these. Idle great and looses power on acceleration under load. Pressure check as Nitro said will confirm.
Put some Berryman's chemtool B-12 in the tank. Good stuff and can't hurt. May be a dirty injector.But kinda sounds like a timing issue. Belt ever done?

Glad you said that.
I have never had a fuel pump go bad or a filter clog, but logically, fuel supply would be adequate at idle but choke off under acceleration with a clogged filter or a weak fuel pump.

NOTE: This happen to me several years back, with the same brand only a Neon. Picked it up cheap at the JY and got it towed home, it only needed a fuel pump, $35 at the local JY and it was up and running, but no power and it sounded like it was sucking a lot of air when you hit the pedal.. Fuel pressure was good, even while running , injectors were fireing. I happen to change the injectors from another car and bingo we were in business.. What happen was the steel band around the fuel pump rusted and the very fine bits of rust (Iron) passed through the so called filter, its just a fine mesh at the pickup, and stopped when they got to the injectors. When I pulled the injectors off the fill tube pipe some injectors were actually full to the top with very fine rust (Iron). That let enough gas through the rust to run smoothly but absolutly no power..
It ran like new after replacing the injectors. May be you can find a good used set off an old motor to try.
